class_docstr: This `Field` represents a list of string tokens.  Before constructing this object, you need
  to tokenize raw strings using a :class:`~allennlp.data.tokenizers.tokenizer.Tokenizer`.
  
  Because string tokens can be represented as indexed arrays in a number of ways, we also take a
  dictionary of :class:`~allennlp.data.token_indexers.token_indexer.TokenIndexer`
  objects that will be used to convert the tokens into indices.
  Each `TokenIndexer` could represent each token as a single ID, or a list of character IDs, or
  something else.
  
  This field will get converted into a dictionary of arrays, one for each `TokenIndexer`.  A
  `SingleIdTokenIndexer` produces an array of shape (num_tokens,), while a
  `TokenCharactersIndexer` produces an array of shape (num_tokens, num_characters).
code: def __str__(self) -> str:
      # Double tab to indent under the header.
      formatted_text = "".join(
          "\t\t" + text + "\n"
          for text in textwrap.wrap(repr(self.tokens), 100)
      )
      if self._token_indexers is not None:
          indexers = {
              name: indexer.__class__.__name__
              for name, indexer in self._token_indexers.items()
          }
